PHS-memory 16GB DDR5 5600MHz ECC UDIMM per ASRock Rack EPYC4000D4U (SP583155)

The PHS-memory SP583155 is a 16GB DDR5 ECC UDIMM engineered for the ASRock Rack EPYC4000D4U server board. Unlike standard desktop memory, this module combines error correction with unbuffered architecture to deliver reliable performance in workstation and entry-server environments that demand data integrity without the latency of registered DIMMs.

Highlights

• 16GB capacity on a single 288-pin DDR5 module
• Runs at 5600 MHz (PC5-44800E) with 1.1V operating voltage
• ECC support detects and corrects single-bit memory errors
• Unbuffered DIMM design for lower latency in compatible systems
• Validated for ASRock Rack EPYC4000D4U platform

In daily use

This module is a direct fit for servers and workstations built around the ASRock Rack EPYC4000D4U. Its ECC capability helps prevent data corruption during long compute tasks, while the 5600 MHz speed provides ample bandwidth for virtualization, database, and content creation workloads. The standard 288-pin DDR5 form factor ensures easy installation in compatible boards.
